How can pigs tell if they have worms, and what are the symptoms of worms in pigs

Pigs in the pig farm will be emaciated after being infected with parasites, malnutrition, reduce the utilization rate of feed, pigs do not eat for a long time, after being infected with lung filaria, there will be obvious respiratory symptoms, coughing and wheezing, if it is infected with erythroids and toxoplasma gondii in summer, there will be high fever, dry manure, coughing and wheezing. Not only that, the migration of internal parasites in pigs can also cause damage to pig tissues and organs, resulting in abscesses and organ lesions in organs or tissues. In addition, parasites will produce toxins that endanger the health of the pig herd, and pigs infected with scabies mites and other body surface parasites will have the phenomenon of itching, hair loss, and dead skin.

Parasites are also often co-infected with other diseases, making it more difficult.

Therefore, deworming work on pig farms is very important. It is recommended that pig farms use ivermectin albendafin compound preparation of anthelmintic drug with better effect, about the choice of deworming method, according to the characteristics of the parasite, I recommend the following methods to carry out deworming work in pig farms.

1.Sow boars are dewormed every 3 months. Deworming 4 times a year.

2.It is recommended to deworm gilts 10 days before introducing the mix.

3.Nursery pigs are dewormed once at the age of 50-60 days and once at the age of 90 days.

4.For the purification of epierythroids and arcuate punches, it is recommended to use tetracyclines and sulfonamides for purification, alternating between summer and autumn and 7-10 days each month.

There are three main ways for pigs to judge that there are insects. The first one: after some pigs have worms, they will have some symptoms of constipation, and the situation is very serious.

Second: Observe some pigs carefully, record the number of times they itch in 15 minutes, and after more than 4 times, they will be insected. The third:

Use homemade salt water for testing, usually 100 ml of hot water with 35 grams of salt.

Worms in pigs generally show slow growth, emaciation, coarse coats, and jaundice.

When eating feed, he often lies on the ground, grinds his teeth and coughs from time to time.

Symptoms such as shortness of breath and blood in the stool. Deworming is one of the important measures for scientific fattening of pigs. What is the best deworming effect?

1.Choose the right anthelmintic medication. Cheap, broad-spectrum, efficient and safe are the key, and there are a complete range of anthelmintic drugs, such as insectatile, anthelminthine, prothhimidazole and levamisole.

At present, it is considered better to have prothhimazole, dosage: 10-20 mg per kilogram of body weight; levamibazole 8 mg per kilogram of body weight; Trichlorfon 80-100 mg per kilogram of body weight. The dosage should not be excessive or insufficient, otherwise the anthelmintic effect will not be achieved.

2.Grasp the time of deworming. Practice has proved that the best effect is to deworm piglets for the first time every month, and then deworm once every 2-3 months. Deworming should be done at night.

3.Choose the right deworming method. Before feeding the deworming drug, let the pig stop feeding, mix the drug and feed at 7-8 o'clock in the evening, and let the pig eat it at one time. If the pig does not eat, a small amount of brine or saccharin can be added to the feed.

Enhance palatability. For group pigs, the dosage should be calculated first, the drug should be crushed, and evenly mixed into the feed. The deworming period is generally 6 days, and captivity feeding should be carried out in a fixed place so that the site can be cleaned and disinfected.

4.Pay attention to the disinfection of the pig barn grounds. After deworming, the feces should be cleaned up in time, piled up and fermented, burned or deeply buried; Floors, walls, and feeding troughs should be filled with 5% lime water.

Disinfect. In order to prevent the excreted worms and eggs from being eaten by pigs and re-infected.

5.Observe the anthelmintic effect. When deworming pigs, they should be carefully observed. If there are symptoms of poisoning such as vomiting and diarrhea, immediately drive the pig out of the slaughter and let it move freely to relieve the poisoning; In severe cases, let them drink half-cooked mung bean soup.

Adage if necessary; For those who have diarrhea, take 50 grams of charcoal or pot bottom ash, mix it into the feed and feed it for 2-3 days. If the deworming effect is not good, you can switch to traditional Chinese medicine to make a gentleman.

10-15 kg piglets can be fed 5-8 grains each time; 20-40 kg medium pigs, feed 10-20 grains each time, and use raw pumpkin seeds at the same time.

Mix into a paste, mix in a small amount of feed to feed the pigs, and feed them twice in a row, 2 grams per kilogram of body weight.

Pig worms are a Sichuan dialect, pig worms are very common in crop fields, and are also known as cabbage worms. The pig insect is about 5 centimeters long, the whole body is dark green, and it is fat, because it looks fat, so the Sichuan people call it the pig worm. If someone says you're a pig, it's either that you're cute or that you're not good-looking.

The symptoms of pigs with insects are generally manifested as long-term emaciation, slow growth caused by poor diet, lying down to eat, cough and shortness of breath, rough and dull pig hair, and blood in feces. To deworm pigs, we should not only prescribe the right medicine, but also pay attention to the time of administration. Early administration can not achieve the effect of deworming, too late will affect the development of pig residue, resulting in pig stiffness.

The deworming time should be determined according to the species, development and season of the worm. Usually the first deworming of pigs is done at the age of the month, so that several parasites can be put together. The winter season is the best season for deworming, and deworming in this season can get twice the result with half the effort.

Precautions for pig raising:

Prevent heatstroke. In summer, the hot weather can easily cause pigs to stop eating due to high fever, so it is necessary to strengthen heatstroke prevention and cooling measures, such as installing sunshade nets, exhaust fans, wet curtain fans and other facilities.

Mosquito and fly repellent. Mosquitoes and flies are rampant in summer, and some diseases are transmitted by blood-sucking insects, such as Japanese encephalitis, epierythrocyte bodies, etc., and measures such as installing mosquito finger killers and using mosquito coils can be taken.

Disinfection and sterilization. In summer, the temperature rises, a large number of drug-resistant bacteria breed, and the cleaning and disinfection of the enclosure is not in place, which is easy to cause bacterial infection of pigs. Therefore, timely cleaning and disinfection is a must, and colleague pen washing can also play a role in cooling.

Pig worm is the larva of the silkworm, also known as "cabbage worm", pig worm can be understood as praising each other for cuteness, and some people use it to satirize others for looking ugly.

The term "pig worm" is popular on the Internet. However, there are many netizens who do not know what "pig worm: what exactly does it mean?" Let's find out.

01 Pig insect is a local dialect in Sichuan, which is a small insect about five centimeters long, with a dark green body and two red whiskers on its head. It generally inhabits green vegetable leaves and specializes in gnawing green vegetable leaves.

02 The popular pig insect saying on the Internet is actually mainly to describe the other party's cuteness and cuteness. On rare occasions, it is also used to satirize the other party's ugly meaning.

03 Pig worms can be eaten. It is rich in high-quality protein and low in fat, and in addition to that, it also contains amino acids that cannot be synthesized by the human body.

04 Pig insects can supplement the nutrients needed by the human body and can be used as a health food. Pig insects also have the effect of repelling cold and nourishing the stomach.

05 Pig worms have the effect of nourishing and strengthening, strengthening the spleen and stomach, and nourishing the liver and kidneys. It is more suitable for forgetfulness, physical weakness, insomnia and dreams, waist and knee soreness and other symptoms.

Expelling parasites in pigs is an important part of the prevention and control of pig diseases. Because the harm of pig parasitic diseases to pigs is particularly serious, the light ones are stunted and slow growth, and the heavy ones form stiff pigs and even die.

According to different ages, physiques, diseases and biological characteristics of parasites, different methods should be adopted to apply appropriate anthelmintic drugs on the basis of symptomatic and improving the resistance of sick pigs.

Deworming is one of the important measures for pig fattening, but it is necessary to master certain skills to obtain better results.

So what are the symptoms of swine parasitic disease? And how to prevent it?

Let's take a look

1. Symptoms of sick pigs.

Pigs with insects generally show slow growth or long-term emaciation, shortness of breath, cough, rough and dull pig hair, lying on the ground to eat, feces with blood, etc., generally more common in 2 6 months old pigs.

Second, choose a good anthelmintic drug.

Nematode drugs include levamisole, mebendazole, trichlorfon, etc.; Anti-trematodes include nitrate meccyanide and thiodichlorophenol; Cysticidal drugs include praziquantel;

Anti-toxoplasmosis includes acetamine and sulfonamides. Powders and tablets are suitable for removing parasites in the digestive tract, injections are suitable for removing parasites in the respiratory system and liver, kidneys and other organs, and emulsions are more suitable for controlling ectoparasites such as ticks and mites.

However, no matter what kind of drug is chosen, replace it with another one after a period of time, so as not to develop resistance and affect the anthelmintic effect.

3. Grasp the timing of deworming.

To deworm pigs, we should not only prescribe the right medicine, but also pay attention to the time of dosing. Too early dosing can not achieve the effect of deworming, too late will affect the development of pigs, the formation of stiff pigs.

The deworming time should be determined according to the species, development and season of the worm.

Usually, the first deworming of pigs is done at the age of one month, so that several parasites can be taken together.

Winter is the best season for deworming, and deworming in this season can get twice the result with half the effort.

4. Fasting before deworming.

In order to facilitate the absorption of anthelmintic drugs by pigs, deworming should be fasted for 12 18 hours before deworming, mix the drug with feed at 7 or 8 o'clock in the evening, let the pigs eat at one time, if the pig does not eat, a small amount of salt water or saccharin can be added to the feed to enhance its palatability;

During the deworming period (generally 6 days), feeding, captivity, defecation, etc., and cleaning and disinfection of the site.

Fifth, the pig house site should be disinfected.

After some pig farmers deworm the pigs, the pig house is not cleaned and disinfected, and the worms and eggs discharged are eaten by the pigs and cause re-infection.

The right thing to do is:

After deworming, the feces should be removed in time, piled up and fermented, burned or buried deeply;

The floors, walls and feeding troughs of the barn should be disinfected with 5% lime water.

6. After deworming pigs, they should be carefully observed.

If there are symptoms of poisoning, such as vomiting and diarrhea, the pigs should be immediately driven out of the barn and allowed to move freely to relieve the symptoms of poisoning;

In severe cases, let them drink half-cooked mung bean soup; For those who have diarrhea, take 50 grams of charcoal or ash at the bottom of the pot, mix it into the feed and feed, and take it for 2 or 3 days to heal.

Pig insect is the larvae of the cabbage butterfly, is a lepidopteran butterfly, its adult body length is 12-20 mm, the body color is black, the chest is densely covered with white and gray-black long hair, the wide wings are white, and the larvae are short and fat, in addition to the cabbage butterfly is mostly active during the day, especially at noon on a sunny day is the most active, pay attention to the larvae to be pupa overwintering.

Pig insect is the larva of the cabbage butterfly, is a lepidopteran butterfly, its adult body length is 12-20 mm, the body color is black, the chest is densely covered with white and gray-black long hairs, the wide wings are white, and the larvae of the cabbage butterfly are short and fat, and the body surface is blue-green.

Butterflies are mostly active during the day, especially at noon on sunny days, and in spring and autumn every year, butterflies will start to breed offspring, at this time butterflies can lay eggs on the back of the leaves that larvae like to eat, in addition, the larvae of the butterfly will turn into pupae for wintering.

The most suitable temperature for the development of rapeseed butterfly is 20-25 degrees, the relative humidity is about 76%, in the case of suitable environment, the egg stage of rapeseed butterfly is 4-8 days, the larval stage is as long as 11-22 days, and the pupal stage is 10 days, and the adult stage is about 5 days, and the growth rate is extremely fast.

When the pig insect has just hatched, the body color is gray-green, and then it turns into blue-green or dark green, the body shape is cylindrical, the middle section is hypertrophied and the back has an inconspicuous yellow intermittent longitudinal line, in addition, the body surface of the pig insect is densely covered with small black hair, pay attention to the feeding habits of the pig insect are more mixed, and feed on nine family plants such as cruciferae, Asteraceae, and spiral flowers.

When the pig insect is first hatched, the body color is gray-green, and then it turns to blue-green or dark green, the body shape is cylindrical, the middle segment is hypertrophied and the back has an inconspicuous yellow interrupted longitudinal line, in addition, the body surface of the pig insect is densely covered with fine black hair, and the individual nodes have four to five transverse wrinkles.

The feeding habits of pig insects are more miscellaneous, mostly feed on nine families of plants such as cruciferous, Asteraceae, and spiral flowers, but they mainly harm cruciferous crops, especially kale, cabbage, cauliflower, etc., pay attention to the pig insects before the third instar, they will gnaw on the leaves on the back of the leaves, and after the third instar, it will turn to the foliar surface to eat.

When cruciferous plants are harmed by pig insects, it is necessary to use insecticide emulsifiable concentrate, insecticide emulsifiable concentrate, high-efficiency pyrocecide emulsifiable concentrate and other pesticides for prevention and control as soon as possible, or stocking natural enemies such as Guang red-eyed bee, reddish velvet cocoon bee, and wind butterfly golden wasp for biological control.
